I tried to add ApproxBayes to Julia@v1.11 and received an ERROR: Unsatisfiable requirements detected for package StatsBase [2913bbd2] message. I retrograded StatsBase to a version within the compatibility window 0.24.0 - 0.33.21 using pkg\> add StatsBase@0.33.21 but got the same error when I tried to add ApproxBayes again. Does anyone have additional information about how to handle this issue? Thanks and here is the whole command and error message: (@v1.11) pkg\> add ApproxBayes Resolving package versions… ERROR: Unsatisfiable requirements detected for package StatsBase [2913bbd2]: StatsBase [2913bbd2] log: ├─possible versions are: 0.24.0 - 0.34.4 or uninstalled ├─restricted by compatibility requirements with ApproxBayes [f5f396d3] to versions: 0.24.0 - 0.33.21 │ └─ApproxBayes [f5f396d3] log: │ ├─possible versions are: 0.1.0 - 0.3.2 or uninstalled │ ├─restricted to versions \* by an explicit requirement, leaving only versions: 0.1.0 - 0.3.2 │ └─restricted by compatibility requirements with DataFrames [a93c6f00] to versions: 0.2.0 - 0.3.2 or uninstalled, leaving only versions: 0.2.0 - 0.3.2 │ └─DataFrames [a93c6f00] log: │ ├─possible versions are: 0.11.7 - 1.7.0 or uninstalled │ └─restricted by compatibility requirements with SortingAlgorithms [a2af1166] to versions: 1.0.0 - 1.7.0 or uninstalled │ └─SortingAlgorithms [a2af1166] log: │ ├─possible versions are: 0.3.0 - 1.2.1 or uninstalled │ ├─restricted by julia compatibility requirements to versions: 1.1.0 - 1.2.1 or uninstalled ├─restricted by compatibility requirements with SortingAlgorithms [a2af1166] to versions: 0.33.7 - 0.34.4 or uninstalled, leaving only versions: 0.33.7 - 0.33.21 │ └─SortingAlgorithms [a2af1166] log: see above └─restricted by compatibility requirements with Distributions [31c24e10] to versions: 0.24.0 - 0.32.2 — no versions left └─Distributions [31c24e10] log: ├─possible versions are: 0.16.0 - 0.25.117 or uninstalled ├─restricted to versions \* by project [fd7fef89], leaving only versions: 0.16.0 - 0.25.117 │ └─project [fd7fef89] log: │ ├─possible versions are: 0.0.0 or uninstalled │ └─project [fd7fef89] is fixed to version 0.0.0 ├─restricted by compatibility requirements with ApproxBayes [f5f396d3] to versions: 0.16.0 - 0.23.12 │ └─ApproxBayes [f5f396d3] log: see above └─restricted by compatibility requirements with FillArrays [1a297f60] to versions: [0.16.0 - 0.21.9, 0.25.49 - 0.25.117] or uninstalled, leaving only versions: 0.16.0 - 0.21.9 └─FillArrays [1a297f60] log: ├─possible versions are: 0.2.0 - 1.13.0 or uninstalled └─restricted by julia compatibility requirements to versions: 0.13.8 - 1.13.0 or uninstalled ---

> [@evmi](#): > > restricted by compatibility requirements with ApproxBayes [f5f396d3] to versions: 0.24.0 - 0.33.21 That’s really odd. I tried the same in an empty project, and got a different error for Distributions.jl, but the net result is the same. What’s odd about the quoted line is that there is no compatiblity setting in the `Project.toml` file of ApproxBayes.jl which restricts StatsBase.jl to versions below 0.33.21. A newer version would work just fine. The same thing happens with Distributions.jl for me: it restricts it below 0.23.12, but the dependencies work just fine with the newest 0.25.117. ApproxBayes.jl hasn’t been updated for a while, but that shouldn’t be an issue. Furthermore, if you run `pkg> dev ApproxBayes`, it adds the dependency just fine. **Update:** apparently, the master version on github is slightly different from the registered 0.3.2 version, in that it has a few compat entries. I don’t see how **adding some restrictions** solves the problem, but apparently it does. **Update 2:** Okay, found it. The problematic compatibility values come from the registry itself. It’s the registry entry of ApproxBayes.jl which limits the versions of StatsBase.jl as \<= 0.33 and Distributions.jl as \<= 0.23. The package should be bumped and reregistered. ---

More specifically, it was [this commit](https://github.com/JuliaRegistries/General/commit/bf2a0455bec8ecbe6fc7acb9ab62b6885a967855) that added these restrictions using RetroCap.jl. ---

I reported the problem to the package maintainer, HTH. > > > Hello! > > The compatibility requirements of the package, as recorded by the Genera…l registry, make it incompatible with Julia 1.11. the compat section in Project.toml should be fully completed, and a bumped version of the package should be added to the General registry in order to make it compatible with Julia 1.11. > > Please see https://discourse.julialang.org/t/unsatisfiable-requirements/125040/2 for more details. > > Thanks!
